How can I get a copy of an old Providence County deed?

Can someone please tell me how I can obtain a copy of a Rhode Island deed?I'm not familiar with this state's archives, and don't know where or how to request something.

A small lot of thatch in North Providence was deeded 3 Sep 1819 from Stephen Steere to Wilbur Smith.The land is supposed to have been inherited from the grantor's paternal grandfather, and could help prove two generations.
